A Linguistic History of Judaism: Yiddish

Written by Kyle Fingerhut

This is the second installment of blogs about Jewish languages. In this post, we’ll discuss Yiddish or mameloshen “mother tongue” as it is affectionately called, a thousand-year-old language first spoken by Jews in Germany.

Origins of Yiddish

Around the tenth century, many French and Italian Jews began to settle in Germany. This group came to be called Ashkenazi Jews. The language this group originally spoke when they arrived in Germany was Laaz, a Judeo-French dialect. As these speakers began to shift to German, they incorporated elements of Laaz and expressions from biblical Hebrew and Aramaic. This language eventually became Yiddish, a name which means, “Jewish” in Yiddish itself. Beginning with the First Crusade in 1096 and increasing with the seemingly endless persecution of Jews thereafter, the effort for Jews to isolate themselves only grew, and having their own language meant they could isolate themselves and try to be left alone.

As Jews began to move Eastward in an effort to avoid persecution in the thirteenth century, they condensed not only in Germany, but also Poland and other Eastern European countries where Yiddish came into contact with various Slavic languages. This had a lasting impact on Yiddish vocabulary, which can therefore be split between Western and Eastern Yiddish (though further distinctions beyond that could be made).

The Golden Age of Yiddish

In the sixteenth century, with the invention of the printing press, texts began to be published in Yiddish, which is written using the Hebrew alphabet. These were written in a version of Yiddish free of dialectical idiosyncrasies to ensure a wide readership.

While Yiddish had increasingly become the language of European Jews, in Germany in the 18th century, members of the Jewish Enlightenment, also known as the Hasklah, campaigned against the use of Yiddish, instead arguing for assimilation and the use of German amongst Jews.

Meanwhile, however, Yiddish only increased in speakership in Eastern Europe. To further this, Hasidic Jews (members of a Jewish group founded in the 18 century from a spiritual revival in contemporary Western Ukraine) used Yiddish heavily, both in religious ceremonies and in day-to-day life. In the 19th century, Yiddish literature burgeoned. These years saw the writings of Sholem Yankev Abramovitsh (whose nom de plume was Mendele Mokher Seforim), I. L. Peretz, and Sholem Aleichem.

Then, efforts to further the use of Yiddish came to a head in 1908, the first conference was held on Yiddish in which the language was declared a “national language of the Jewish people”. The purpose of the meeting was to further advance the use of Yiddish in education, standardized Yiddish spelling, funding of cultural institutions, etc. Unfortunately, not much was accomplished in the way of the practical advancement of the language. Instead, attendees mainly debated whether or not Yiddish was a or the "national language of the Jewish people".

The Fall of Yiddish

In the Soviet Union, the government once supported Yiddish schools, theater, and literature as long as it was not religious in nature. However, this was eventually ended by the government and institutions were shut down. As Joseph Stalin viewed Yiddish as anti-soviet, many Yiddish writers were imprisoned or executed during the purges of 1937. Another similar incident was the murdering of many other Yiddish writers on the Night of the Murdered Poets.

Prior to the Holocaust, there were 13 million speakers of Yiddish. However, 85% of the six million Jews murdered in the Holocaust were Yiddish speakers. In 2021 there was an estimated speakership of 600,000. Therefore, the language is currently considered “definitely endangered” by the UNESCO Atlas of the World's Languages in Danger.

Further leading to the decrease in Yiddish speakership, when Israel was founded in 1948, Yiddish was largely suppressed in order to promote Hebrew, even going so far as taxing Yiddish theater in an effort to unify all Jews under Hebrew. Yiddish was seen as a language that was unique to European Jews and which couldn’t be used as Hebrew to unite all Jews of innumerable backgrounds. Likewise, many wanted to leave behind any Germanic traces due to the traumas of the Holocaust.

As a further blow to Yiddish, those who immigrated to the United States were eager to assimilate and adopt English, especially for their children. As an example, my Bubbe (Yiddish for grandmother) and Zayde (Yiddish for grandfather) were both born in the United States to Ukrainian Jewish parents. My great-grandparents taught my Bubbe and Zayde Yiddish, however, for reasons that are now unclear to my Bubbe, she and my Zayde never taught Yiddish to their three children. Though my Bubbe adores Yiddish and continues to attend a weekly Yiddish club with a group of other women in Maryland, it seems abundantly clear that the population of young Jews who speak Yiddish is on a steep decline.

Nowadays, Eastern Yiddish is the most common dialect. It continues to be spoken, most frequently by Ultra-Orthodox Jews in New York and Israel. Though Yiddish has lost the status it once possessed, a revival is taking place. Not only is Yiddish on Duolingo (and the course is wonderfully thorough), but there is an abundance of both old and new Yiddish music and literature out there.

Examples of Yiddish

Yiddish is claimed to be made up of roughly 80% German and 20% Hebrew with a good amount of Slavic words thrown in depending on the variety. Therefore, for most Germans, Yiddish is more or less intelligible and sounds quite similar to certain regional varieties of German, though the Hebrew and Slavic components are, of course, unintelligible.

Though Yiddish is regrettably falling out of use, it has left an indelible mark on many languages where Jews have been present. For the sake of relevance, I’ll talk about English and Dutch. In English, the words chutzpah, bagel, glitch, klutz, kvetch, mensch, schmuck are all, among many others, of Yiddish origin. In Dutch, the words Mokum (slang for “Amsterdam”), gannef “thief”, gabber “friend”, lef “courage”, mazzel “luck”, sores “misery”, ponem “face” are all, among many others, of Yiddish origin.

As an example of Yiddish words as compared with German, Hebrew, and Slavic languages, we can examine the following:

Though Yiddish was once regarded by many as a corrupt jargon version of German, today it is still receiving attention from learners who wish to revive their ancestral language and even German linguists who wish to examine ancient facets of German only preserved in Yiddish. Likewise, many universities offer Yiddish courses and as of February 2023, Yiddish will even be taught at the University of Amsterdam. Click here for information on that.

If you’re interested in learning Yiddish or just want to hear what it sounds like, I can recommend Duolingo and share a playlist of some Yiddish songs that I like at this link.
